Constructed with a fiberglass inner liner and an outer jacket treated to resist UV degradation, this duct runs 18 inches in diameter and 25 feet in length per bag. The R-6 insulation value meets common energy code minimums for unconditioned space installations such as attics and crawlspaces. HVAC installers and sheet metal mechanics use this product to connect air handlers, plenums, and register boxes in low-pressure supply and return air applications.\u003c\/p\u003e\n\u003cp\u003eThis flex duct is suited for residential new construction and retrofit HVAC projects where flexible routing is needed around obstructions or where rigid ductwork is impractical. The 18-inch diameter accommodates high-volume trunk or branch runs in larger residential systems or light commercial applications. The UV-inhibited outer jacket makes it appropriate for installations with incidental light exposure, including open attic spaces. The black outer jacket is standard for this product configuration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eR-6 insulation rating meets energy code requirements for ducts in unconditioned spaces\u003c\/li\u003e\n  \u003cli\u003e18-inch diameter supports high-volume air distribution runs\u003c\/li\u003e\n  \u003cli\u003e25-foot length per bag reduces splice points in longer runs\u003c\/li\u003e\n  \u003cli\u003eUV-inhibited outer jacket resists degradation in attic and exposed installations\u003c\/li\u003e\n  \u003cli\u003eFiberglass construction provides thermal and acoustic performance\u003c\/li\u003e\n  \u003cli\u003eBlack outer jacket for standard HVAC flex duct applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation flexible air duct for residential and light commercial low-pressure HVAC supply and return systems using standard 18-inch duct collars and fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eLicensed HVAC technicians and sheet metal mechanics install flexible duct in accordance with SMACNA guidelines and local mechanical codes. Power down and lock out the air handling unit before cutting into or connecting duct sections. Secure all connections with approved clamps and mastic or metal tape rated for duct use — do not use standard cloth-backed tape. Avoid sharp bends or compression of the duct, as either condition significantly reduces airflow and system efficiency.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Rating\u003c\/strong\u003e: R-6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 25 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Jacket\u003c\/strong\u003e: UV-inhibited, black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Material\u003c\/strong\u003e: Fiberglass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions (L x W x H)\u003c\/strong\u003e: 39 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FLEXDUCT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1860\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FLEXDUCT","offers":[{"title":"Default Title","offer_id":51506818122034,"sku":"1860","price":143.37,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/flexduct-1860-flex-air-duct-r-6-18-in-25-ft-fiberglass","provider":"Voomi Supply","version":"1.0","type":"link"}
